For the liar, he could be a con - artist type of character who has been living a double life. He might be pretending to be someone he's not in order to gain something, like money or status. His lover could be a journalist who is investigating a story and accidentally falls for him. Another possible main character could be the liar's ex - partner who still has some influence on his life and causes trouble for his new relationship with his lover. And don't forget the family members of the lover who play a role in either supporting or opposing the relationship.
The main characters could be a young man who lies because he's ashamed of his real identity. He could be from a poor background but has created a false persona. His lover could be a wealthy heiress who doesn't care about his background but is hurt by his lies. Additionally, there could be a mentor figure in the liar's life who taught him to lie in the first place, and this character could add more depth to the story. There could also be a group of friends that the couple hangs out with, and each of them has their own reaction to the liar's lies and the relationship.
The obvious main characters would be the liar and his lover. The liar could be a charming but troubled young man, perhaps an artist who lies about his past to seem more interesting. His lover could be a kind - hearted girl, a student or a young professional, who is initially drawn to his charm. There could also be a best friend character who suspects the liar's true nature and tries to warn the lover.
There could be characters who are on the periphery of the main relationship in the original story but become central in the side story. Maybe a rival of the liar for the lover's affection, or a mentor - like figure who tries to guide one of the main characters in a different direction. These characters would be important as they would drive the plot of the side story forward, adding new twists and turns to the narrative.
Since it's a side story, it could be delving into the lives of secondary characters. It might explore how they are affected by the relationship between the liar and his lover. For example, it could show how a friend of the liar or the lover reacts to their relationship, or it could uncover some secrets about the setting or other elements related to the main story that haven't been fully explored in the main plot.
I don't have enough information to tell who the main characters are. It could be a liar, of course, and perhaps the people who are affected by the liar's lies.
One idea could be exploring the backstory of the liar. Maybe he had a difficult childhood that led him to be untruthful. For example, he grew up in a family where honesty was not rewarded. Another could be focusing on how the lover discovers the lies bit by bit. It could start with small things like forgotten promises and gradually lead to bigger revelations. And a third idea is to have a parallel story of another couple in the same universe, whose relationship is affected by the liar and his lover's situation.
A popular choice could be a brooding dark elf as the dark mystic lover. He could be paired with a brave and curious human maiden. The contrast between their species and personalities would create a lot of interesting dynamics in the story.
I'm not entirely sure as I haven't watched it myself. But generally, it might be about the side events or the backstories of the characters from the main 'watch the liar and his lover' story.
I don't know since I haven't read the novel. It could be the liar themselves as the central character, and perhaps those who are being deceived by the liar.
I'm not sure as I haven't read the novel. But usually in a love - centered novel, there would be the two lovers as main characters. Maybe a male and a female lead.
It could be a young couple who were separated due to family issues. For example, the boy's family didn't approve of the girl and they were forced apart. Then the main characters would be the boy and the girl.
Since it's called 'the good liar novel', the main character is most likely the liar himself. There might also be characters who are his victims, friends, or family members. These other characters could play important roles in either enabling his lies or trying to uncover them. For example, there could be a detective - like character if it's a mystery - themed novel who is determined to expose the liar.
